Thunderbird IMAP Migration problem
First congratulations on a fine product.
I'm currently evaluating Zimbra and am having trouble migrating my Thunderbird mbox email.
I'm simply dragging the folder root from Local Folders to my IMAP account.
Thunderbird happily sets off copying folders and emails which I can see in Zimbra Webmail. The problem is that part way in to the copy (perhaps < 10%) the copy stops. There are no error messages in Thunderbird.
Is there a debug mode in Thunderbird or a log file in Zimbra that might give a clue?
Is there a more failsafe way to migrate my folders?
Many thanks in anticipation
Server to Server - use imapsync for IMAP Migrations
MAILS ON OLD IMAP SERVER
Do you have still IMAP access to the oldemail server?
If yes, then you couldperform a server to server migration.
Search on the forum, wiki and google for the unix script tool 'imapsync'.
Works fine for me to do IMAP migrations. But take cre about the exact options needed to conserver the 'received at' date.
MAILS IN THUNDERBIRD ONLY
If you only have the emails in Thunderbird, try to reduce the number of connections. In Thunderbird Menu > Extras > Options > Advanced > about:config advanced settings
Search for the key's containing 'connect' or 'imap'.
I found that thunderbird chokes on empty folders
I had the same thing happen. I finally figured out that thunderbird would hang during the copy to Zimbra if there were subfolders but no messages in the folder. The only solution I could come up with was to drop a dummy message in all empty folders.
I'm still looking for a solution to the fact that all of my message have been time-stamped in zimbra according to when I copies them to the server, not the actual message date.
I just found that answer in another forum
Thanks NOZIL, ironically, I just stumbled across that answer in another forum. I've been experimenting with that switch and it works wonders. I'm actually moving between two zimbra servers and the switch is even correcting messages that got messed up in the original migration. Life is good. Zimbra Rules!
